Camera Operation
Advance spin wheel
is spun to advance
the film and wind
the shutter.
(Energy Processing)
When the main
Capacitor is charged
it is indicated by a LED
light and its voltage is
applied to the flash
tube terminals.
Frame counter is
advanced to show the
number of pictures left.
Film and shutter are in
position to use the
camera.
(Material Processing)
(Material Processing)
The 1.5V AA battery
cell powers up the
oscillator.
The first transformer
generates the AC
Voltage to 200-300 volts.
(Energy Processing)
(Energy Processing)
(Signal Processing)
The shutter closes and
the image is stored onto
the camera.
(Energy Processing)
User looks through
the viewfinder to
select the image.
The trigger switch is
pressed to activate
the shutter and the
flash charge.
(Energy Processing)
(Signal Processing)
The shutter opens and the voltage
travels to a second transformer. This
new and much higher voltage is then
put through the flash tube to create a
flash.
